Please note! The asymmetry of the LR3 and LR4 are not exactly the same. The table at the top of this thread was designed for the LR3. To get a sense of the actual asymmetry of the LR4, consider this post by Ryan of V1 Engineering, showing an affordable and doable way to get a full size table for an LR4: ~ $200 Full sized Lowrider table, Non-CNC Build
If you take his newer asymmetry in that newer table design, I think you will be happier.
My LR4 is still riding on a table that was designed for LR3, and thus its cuttable area is not centered perfectly, and thus not as usable as I’d like.
